Surface map of Luhman 16B recreated from VLT observations. ESO's Very Large Telescope has been used to create the first ever map of the weather on the surface of the nearest brown dwarf to Earth. The figure shows the object at six equally spaced times as it rotates once on its axis

Artist's impression of the newly discovered star WISE J085510.83-071442.5, the coldest known brown dwarf star.
Brown dwarfs are dim star-like bodies that lack the mass to burn nuclear fuel as other stars do.The new star is the fourth closest to our Sun, at 7.2 light-years from Earth.
